20569224 S3 Crankshaft Flange for Volvo FM12

What does a crankshaft flange do?

This compressor crankshaft flange serves as a critical component in the air brake compressor assembly, ensuring the stable transmission of power from the crankshaft to the compressor drive mechanism. Constructed with high-strength components, it is engineered to withstand the intense pressure and constant motion found in heavy commercial vehicle braking systems.

Compatible Volvo FM12 vehicles

This component is specifically fitted to Volvo FM12 series vehicles, including the FM 12/380, FM 12/460, FM 12H/340, and FM 12H/380 models. It also provides compatibility for the FM 12/420, FM 12/340, and FM 12H/420 variants to ensure precise operation across different engine power outputs.

Installation and maintenance guidance

For correct installation, technicians should verify the pilot diameter, bolt hole circle, and seal seat size against the existing unit. Ensuring these dimensions match is vital to prevent air leakage or excessive vibration during operation. Regular inspection of the flange and its mounting points is recommended during routine compressor maintenance to prevent system failure.

Selection and troubleshooting

Selecting the correct flange based on the specific compressor type is essential for maintaining system integrity in heavy-duty applications.
